CMC amfani a abinci
Sodium carboxymethyl cellulose (carboxymethyl cellulose, sodium CMC) wani carboxymethylated samu daga cellulose, kuma aka sani da cellulose danko, kuma shi ne mafi muhimmanci ionic cellulose danko.
CMC galibi wani fili ne na polymer anionic wanda aka samu ta hanyar amsa cellulose na halitta tare da caustic alkali da monochloroacetic acid. Nauyin kwayoyin halitta na fili ya fito daga dubu da yawa zuwa miliyan daya. kullin kwayar halitta
CMC na cikin gyare-gyaren cellulose na halitta. A halin yanzu, Hukumar Abinci da Aikin Noma ta Majalisar Dinkin Duniya (FAO) da Hukumar Lafiya ta Duniya (WHO) sun kira ta a hukumance "cellulose da aka gyara". Hanyar hada sodium carboxymethyl cellulose ta Jamus E.Jansen ne ya ƙirƙira a cikin 1918, kuma an ƙirƙira shi a cikin 1921 kuma an sanar da duniya, tun daga lokacin ana kasuwanci da shi a Turai.
An yi amfani da CMC ne kawai don samfuran ɗanyen, azaman colloid da ɗaure. Daga 1936 zuwa 1941, binciken aikace-aikacen masana'antu na sodium carboxymethyl cellulose ya kasance mai aiki sosai, kuma an buga wasu haƙƙoƙin haɓakawa da yawa. A lokacin yakin duniya na biyu, Jamus ta yi amfani da CMC a cikin kayan wanka na roba a matsayin wakili na anti-reposition, Kuma a matsayin maye gurbin wasu gumakan halitta (kamar gelatin, danko arabic), masana'antar CMC ta haɓaka sosai.
Ana amfani da CMC sosai a cikin man fetur, ilimin ƙasa, sinadarai na yau da kullun, abinci, magani da sauran masana'antu, waɗanda aka sani da "monosodium glutamate masana'antu".

Kaddarorin tsarin CMC
CMC fari ne ko ɗan rawaya foda, granular ko fibrous m. Wani sinadari ne na macromolecular wanda zai iya sha ruwa ya kumbura. Lokacin da ya kumbura cikin ruwa, zai iya samar da manne mai haske. Matsakaicin pH na dakatarwar ruwa shine 6.5-8.5. Abun ba shi da narkewa a cikin kaushi na halitta kamar ethanol, ether, acetone da chloroform.
CMC mai ƙarfi yana da kwanciyar hankali ga haske da zafin jiki, kuma ana iya adana shi na dogon lokaci a cikin busassun yanayi. CMC wani nau'i ne na ether cellulose. Yawancin lokaci ana yin shi daga ɗan gajeren auduga (abin ciki na cellulose har zuwa 98%) ko ɓangaren litattafan almara na itace, wanda aka yi masa magani da sodium hydroxide sannan a mayar da shi da sodium monochloroacetate. Nauyin kwayoyin halitta na fili shine 6400 (± 1000). Yawancin hanyoyin shirye-shirye guda biyu ne: hanyar kwal-ruwa da hanyar ƙarfi. Akwai kuma sauran filayen shuka da ake amfani da su don yin CMC.

CMC ba kawai mai kyau emulsion stabilizer da thickener a cikin aikace-aikace na abinci, amma kuma yana da kyau kwarai daskarewa da narkewa da kwanciyar hankali, kuma zai iya inganta dandano na samfurin da kuma tsawanta lokacin ajiya.
A cikin 1974, Hukumar Abinci da Aikin Noma ta Majalisar Dinkin Duniya (FAO) da Hukumar Lafiya ta Duniya (WHO) sun amince da amfani da CMC mai tsafta don abinci bayan tsauraran bincike da gwaje-gwajen halittu da guba. Ma'aunin aminci na duniya (ADI) shine nauyin jiki 25mg/kg/kg/rana.
2.1 Thicking da emulsification kwanciyar hankali
Cin CMC na iya taka rawa wajen haɓakawa da daidaita abubuwan sha da ke ɗauke da mai da furotin. Wannan shi ne saboda CMC ya zama colloid mai tsabta mai tsabta bayan an narkar da shi a cikin ruwa, kuma ƙwayoyin sunadaran suna zama barbashi tare da caji iri ɗaya a ƙarƙashin kariya na fim din colloid, wanda zai iya sa kwayoyin sunadaran suna cikin kwanciyar hankali. Har ila yau, yana da wani sakamako na emulsification, don haka a lokaci guda, zai iya rage tashin hankali a tsakanin mai da ruwa, don haka kitsen zai iya zama cikakke emulsified.
CMC na iya inganta kwanciyar hankali na samfurin saboda lokacin da ƙimar pH na samfurin ya ɓace daga ma'anar isoelectric na furotin, sodium carboxymethyl cellulose zai iya samar da tsari mai rikitarwa tare da furotin, wanda zai iya inganta kwanciyar hankali na samfurin.
